Frontage Road Construction Update

Frenchtown Neighbors,

The Montana Department of Transportation will continue reconstruction on the Frenchtown Frontage Road. Shared-use path paving and approach work will be taking place intermittently throughout the week, from the Frenchtown irrigation ditch to Loiselle Lane. Paving is anticipated to last throughout the month of August. 

Paving will continue to impact residents with driveways and approaches directly off of the Frontage Road in areas where work is being completed. Delays of up to 20 minutes can be expected while crews pave the roadway in front of residences. Once the material has been placed and is properly compacted, access will be regained.

Additional signage and flaggers will be in-place to facilitate safe travel and to provide access during these periods of paving. Those who will be directly impacted will have a sign at the intersection of their property and the Frontage Road directing drivers to wait for a pilot car. Poteet Construction may be placing signs along property approaches the night before paving is anticipated, but please rest assured that paving will only be occurring between 8 a.m. and 4:30 p.m. or after 6:30 p.m. after Monday and Tuesday. If that sign is not on your property, please proceed as you have been during regular construction, being mindful of additional construction vehicles, workers, and all posted signage.

Once paving has been completed, flaggers will be directing drivers from the Frontage Road in or out of their property. Work at each approach is anticipated to last 20 minutes. As soon as paving in front of your property is complete, no additional delays are anticipated to access the Frontage Road from residential areas.

Flaggers and crews will make every effort to minimize impacts and to provide alternative routes where possible. Please slow in these active construction areas to be alert for additional workers on the Frontage Road.

Dirt work will continue on the Frontage Road progressing to the east.

The shared-use path will be closed to the public until further notice due to heavy equipment working in the area.

Pedestrian and cyclist traffic is advised not to use the Frontage Road in this area as an alternative route due to the loss of pavement. Heavy equipment is near and on the roadway which makes it unsafe for foot traffic.

As a reminder, the posted speed limit for the Frenchtown Frontage Road construction is 35 MPH.

Interstate 90 traffic has been moved to both sides of the interstate. Speed limits will be 65 both directions. Median work is still continuing but traffic crossovers have been removed. Please be alert and pay attention to traffic signage.
